Intel "Panther Lake" Processor to Integrate a "Celestial" Xe3 iGPU
"Panther Lake" is the codename for the microarchitecture behind Intel's 17th Gen Core processors due for 2026-27. It succeeds the 16th Gen "Lunar Lake" (2025-26), 15th Gen "Arrow Lake" (2024-25); and 14th Gen "Meteor Lake" (2023-24) architectures. While very little is known about "Panther Lake," the first piece of information discovered in the LinkedIn profile page of one Intel Graphics engineer, suggests that the graphics tile of the processor will feature an iGPU based on the Xe3 "Celestial" graphics architecture, which is two generations ahead of the current Xe "Alchemist," and one ahead of Xe2 "Battlemage."
Intel's graphics architectures will continue to be highly scalable and modular in their applications, with variants of them scaling between low-power iGPUs to large client discrete GPUs, and very-large HPC-AI processors. The variant for the iGPU powering "Panther Lake" will be Xe3-LPG, a highly skimmed version of the architecture for lower Xe Core counts, with just the right hardware to operate in power-constrained devices such as mobile processors. From the looks of it, Intel will stick with the disaggregated chiplet design for its processor architectures going all the way down to "Panther Lake," as an older company slide detailing the scalability of "Celestial" highlighted a "next platform" processor succeeding "Meteor Lake" and its immediate successor ("Arrow Lake").

Given Intel's recent form releasing stuff I'll definitely await reviews :p :) : D
But it does seem like the Dgpu ship is sailing.
pretty sure panthers hate water lol
Meteor lake: Officially "2H 2023"this writer claims 2023-2024. OneRaichu reports that ES2 has already achieved the expected performance and will launch in September 2023 based on the general lead time.
Arrow lake: Officially "2024" but this writer claims 2024-25.
Lunar Lake: Officially "2024+" but this writer claims 2025-26. It has been announced that the first samples have already been taped out, and based on the general lead time, it will launch in two years, from the end of 2024 to the beginning of 2025.
However, they DO hate getting into water, unless absolutely necessary to either avoid a predator or to obtain food....
But OTOH, some parts of the world are already running low on water, so intel must stop using up all our lakes, hehehe :)
Now let's hear about Zen 7 and RDNA5 shall we.
2nd yr - silicon validation stage
3rd yr - package validation stage (incl. ES, QS, etc.)
A leaker reports that Meteor lake is 1/3 of the way through the package validation stage. Lunar lake has finished the design stage and is about to enter the silicon validation stage, according to Intel's official explanation. They avoided next generation EUV on finalizing the 20A/18A design, but I think their priority is to ensure that the schedule is kept.
There is no doubt that they are keeping things on schedule with Meteor lake and Lunar lake being released a year and a half apart. If Arrow lake is sandwiched in between, they launch new generation every 9 months (just for laptops, interval between the 12/13 generation was 9 months respectively and that between 13/14 gen will be the same).
However, it is still too much to ask, and it will not be possible to make it without organizing one of them as mobile-only and the other as desktop-only. I personally find it more interesting that the Arrow lake name was not mentioned in the earnings presentation.
this is what Intel GPU naming scheme inspire to me ...
tho i am happy they improved the performances from "total [censored]" to "acceptable" and slashed prices from "eh? they ask that much for that?" to "well ... they should have gone for that from the start"
on the other hand ... yay better IGP, it will be better (at least) than Intel current IGP? right? (well that's not too hard i confess )
